Yes but what do you want to know?
Trekkers are the best but carry extra bolts. they unscrew sometimes. Local hardware store.
A bit heavy too. If your setup is heavy then you can get tired easily. best to setup light, ie light skis with light binders. din 14s although very good can get heavy. also when not going uphill they can be tricky to stay balanced on. DONT LEAN FORWARD ON SLIGHT DOWNHILLS you will go over.
secure fix unless yu get em for under 50 can dollars I wouldnt waste my money on them. that design is 15 years old
P.S. JAPAN HAS SICK POWDER
